Description The implementation of novel breeding technologies is expected to contribute substantial improvements in crop
productivity. While conventional breeding methods have led to development of more than 200 improved chickpea varieties
in the past, still there is ample scope to increase productivity. It is predicted that integration of modern genomic resources
with conventional breeding efforts will help in the delivery of climate-resilient chickpea varieties in comparatively less
time. Recent advances in genomics tools and technologies have facilitated the generation of large-scale sequencing and
genotyping data sets in chickpea. Combined analysis of high-resolution phenotypic and genetic data is paving the way for
identifying genes and biological pathways associated with breeding-related traits. Genomics technologies have been used
to develop diagnostic markers for use in marker-assisted backcrossing programmes, which have yielded several molecular
breeding products in chickpea. We anticipate that a sequence-based holistic breeding approach, including the integration of
functional omics, parental selection, forward breeding and genome-wide selection, will bring a paradigm shift in development
of superior chickpea varieties. There is a need to integrate the knowledge generated by modern genomics technologies
with molecular breeding efforts to bridge the genome-to-phenome gap. Here, we review recent advances that have led to new
possibilities for developing and screening breeding populations, and provide strategies for enhancing the selection efficiency
and accelerating the rate of genetic gain in chickpea.
